Nasa launches saucer-shaped vehicle to test technology for landing on Mars Nasa launches saucer-shaped vehicle to test technology for landing on Mars
(about 2 hours later)
After several weather delays, Nasa on Saturday launched a helium balloon carrying a saucer-shaped vehicle high in Earth's atmosphere to test technology that could be used to land on Mars. A saucer-shaped Nasa vehicle launched by balloon high into Earth's
Since the twin Viking spacecraft landed on the red planet in 1976, Nasa has relied on the same parachute design to slow landers and rovers after piercing through the thin Martian atmosphere. atmosphere splashed down in the Pacific Ocean on Saturday, completing a
The $150m experimental flight tests a novel vehicle and a giant parachute designed to deliver heavier spacecraft and eventually astronauts. successful test of technology that could be used to land on Mars.
Viewers around the world with an internet connection followed portions of the mission in real time thanks to telescopic cameras on the ground. Later in the mission, cameras on board the vehicle should turn on and beam back low-resolution footage. Since the twin Viking spacecraft landed on the red planet in 1976, Nasa
After taking off at 11.40am from the Pacific Missile Range Facility on the Hawaiian island of Kauai, the balloon boosted the disc-shaped vehicle over the Pacific. Its rocket motor should then ignite, carrying the vehicle to 34 miles high at supersonic speeds. has relied on the same parachute design to slow landers and rovers after
The environment at this height is similar to the thin Martian atmosphere. As the vehicle prepares to drop back to Earth, a tube around it should expand, like a Hawaiian puffer fish, creating atmospheric drag to dramatically slow it down from Mach 4, or four times the speed of sound. piercing through the thin Martian atmosphere.
Then the parachute should unfurl and guide the vehicle to an ocean splashdown. At 110ft in diameter, the parachute is twice as big as the one that carried the one-ton Curiosity rover through the Martian atmosphere in 2011. The $150m experimental flight tested a novel vehicle and a giant
The test was postponed six previous times because of high winds. Winds need to be calm so that the balloon doesn't stray into no-fly zones. parachute designed to deliver heavier spacecraft and eventually

"We want to test them here, where it's cheaper, before we send it to Mars to make sure that it's going to work there," project manager Mark Adler of the Nasa Jet Propulsion Laboratory said during a pre-launch news conference in Kauai in early June. Despite small problems such as the giant parachute not deploying fully, Nasa deemed the mission a success. "What we just saw was a really good test," said Nasa engineer Dan Coatta
